Catholic Mass attendance in the province of Barcelona has doubled over the past five years. According to data from the Centre d’Estudis d’Opinió and from Idescat published and commented on the Archdiocese of Barcelona’s website, in July 2020, just over 300,000 people attended Mass with varying frequency, while in July 2025, the number of people attending Mass increased to over 600,000. In percentage terms, Mass attendance rose from 10.4% in 2020 to 20.1% in 2025. The attendance figures only refer to Catholic services. The number of Catholics in the province has also increased by more than 200,000 people, from 3 million (52.9% out of 5.7 million) in 2020 to 3.25 million (54.4% out of 5.975 million) in 2025. If we add to the usual attendance figures the number of people who attended Mass at least once during the year, an additional 400,000 Catholic faithful should be counted in between 2020 and 2025. In other words, “if in the current year (2025) we add these 400,000 occasional churchgoers to the over 600,000 regular churchgoers, we reach one million people”, the Archdiocese points out on its website. This reflects “a general increase in religious service attendance by the different confessions present in Catalonia after the COVID-19 pandemic”, the website further specifies.
